An open source Java-based Search engine

Elasticsearch is a search engine based on Apache Lucene and written in Java. It’s open-source and uses REST APIs for implementing Lucene features. It has an indexing framework built on top of the Lucene Standard analyzer and uses optimized data structures for read and write performance.

It’s simple to set up and has a short learning curve. It doesn’t have a regular schema and indexes the data with data types corresponding to their mapping details(documents). You can add other search features such as autocompletion, instant search, and query suggestions. You can also create an alert engine through the Elasticsearch Alerting tree application – SentiNL. 

It also has advanced search features such as thread pools, node monitoring, and cluster management. You can use Elasticsearch in various applications such as e-commerce searching, recommendation engines, system log monitoring, management, and a long etcetera.

Why is Elasticsearch so fast?

Elasticsearch is based on Lucene, so it works well for full-text search. It’s also a near-real-time search platform, which implies that the delay between indexed and searchable content is normally less than a second. It doesn’t use standard normalization techniques, and you can access data through documents (metadata).

The reason for its fast performance is in how it approaches the searches. Elasticsearch first breaks your input data into small units through its analyzer and creates tokens along with documents. Then the tokens are run through its distributed inverted indices. When you send a query to the system, the algorithm loops back the replicated results from data shards. Percolators (reverse search models) are often used to return cache saved data without searching through the whole system.

What is Elasticsearch used for?

  • Search

    One of the biggest uses of Elasticsearch is for searching, i.e., test search, logic search, fuzzy search, match search, and other search types. Elasticsearch uses Filter cache, i.e., indexing and scoring documents to store in a faster memory for easier retrieval. It uses a bottom-up approach and can be used to display relevant results. Elasticsearch can take in numerous wells of data to keep them accessible.

  • Real-Time Analysis

    Elasticsearch has tools that you can use to scrape and combine public data. A developer can use that data to create different real-time analytics boards for investigation and monitoring. Companies use Elasticsearch for log investigation, ease of indexing, and screening client care activity such as customer behaviors.

    One of the biggest uses of Elasticsearch analytics is in geo monitoring and reporting. Elasticsearch is highly suitable for performing optimization searching on geospatial data and numbers. It uses advanced binary search algorithms for geo analysis.

  • Big Data searching

    You can use Elasticsearch API​​ or extraction tools (such as Logstash) to submit the data and retrieve data as JSON documents. The Elasticsearch API can be used to retrieve documents in Big Data. It has special Hadoop-ES connectors for real-time searching of big data.

  • Data visualization

    Elasticsearch has a lot of graphing tools you can use. One particularly popular tool is Kibana, which has options for charting and geodata servicing. Through Kibana, you can display data through histograms, sunbursts, pie charts, and more.

  • Machine Learning

    Many companies use Elasticsearch for its full-text searchability and inquiry rundowns. It can also be used to apply machine learning algorithms to the data. Anomaly and outlier detection is easy with Elasticsearch’s time series modeling techniques. You can also apply regression, classification, and log index through this.
